scope:

This part of IEC 60873 provides methods for determining the performance of all electrical and pneumatic analogue chart recorders operating from a standardized signal which may be used in process control. It is intended that continuous and dotted-line traces, multiple-pen and multiple-channel instruments should be covered. Some tests should not apply to all instruments and additional tests may be required for certain types of recorders. The object of this standard is to specify uniform methods of test for the evaluation of the performance of electrical and pneumatic analogue chart recorders operating from a standardized signal which may be used in process control. When a full evaluation in accordance with this standard is not required, those tests which are required should be performed and the results reported in accordance with those parts of the standard which are relevant. It should be made clear in such a report that the evaluation reported is not a full evaluation and the parts omitted should be indicated.
